I grew the hybrid rugosa Agnes in zone 6b where it did very well. The shade of yellow is much paler, but it can be an interesting rose to grow because it does have typical rugosa foliage, the flowers have a distinctive pleasant fragrance, and it is almost always the first rose to bloom in the spring, lengthening the rose season. I don't think it repeats. And I wouldn't call it especially generous with its flowers, but it can charm when in bloom and it is an easy care rose.
For a richer yellow it's hard to beat Autumn Sunset, IMO. It does build up quickly into a large shrub.
Another Ralph Moore introduction is Rise 'n' Shine It's also a mini. It's said to grow to about 4 ft in each direction. In fall the colors of the flowers are quite saturated. Bloom in warm weather can be almost milky pale. But in all cases the small flowers are formally shaped and decorative. It's densely branched and looks handsome in the garden even when not in bloom. Here in zone 7 it's almost evergreen.
Finally, I grew Midas Touch in zone 6b and while I don't usually recommend HT roses - especially for zone 5 weather, MT is a tough rose with saturated, non-fading yellow flowers. It looks good planted with other flowers and does well there. I planted it with blue salvia jurisicii which bloomed at the same time and covered up the bottom 1/3 of the leggy plant, and with iris. And they all looked great together.
